I've been reading on the trailblazer forum and searching the web for this info. There are ODB-II bluetooth readers on Ebay for around $20 and various apps in the Android or possibly Itunes marketplace that allow you to monitor a number of engine diagnostics on your phone. One of them should be transmission temparature. Torque seems to be the most common app for this. Has anyone used this combination on an Acadia and been able to get it to work specifically for transmission oil temp?

After much research my wife and I have taken the plunge and bought a 2011 Acadia SLT-2. I was worried about towing since we are downsizing from a Suburban which always towed our toys without breaking a sweat. We plan to tow jetskis about 360 miles round trip over only slightly hilly terrain. The loaded trailer should way no more than 2,500 lbs and we do have the tow package. Everything I've read says the Acadia should tow this without any trouble but I would love the piece of mind of having a transmission temperature gauge on the trip.

Anyone done this and made it work? Also, where is the ODB-II plug on an Acadia (we haven't picked ours up yet to even look for it).

The Scangauge II is really cool. I have it on my 02 Silverado and have it set to read transmission temp, instant MPG, distance to empty and Oil life monitor. I need to get another cord so I can plug it into the Acadia and see the transmission temp on ours. Right now I have it permanently mounted in the truck so I can't just pull the cord out. Here is the link

It definitely worked. I had to change the units from celcius to farenheit. It registered a different temp than the coolant temp which was one of the reported problems so to me that means it's giving an accurate reading and not just copying the coolant temp. I did get a fault showing that my OBD2 reader was faulty but the Torque web site warns that the cheap ones from overseas sold on Ebay can be a little buggy. I may now invest in a good quality reader since I know it works.

Can you give us the details on what you had to buy and how you hooked it up? I have a Droid and would love to get it to do this for me.

I bought a $20 reader from Ebay and downloaded the paid version of "Torque Pro" from the google marketplace. Torque has a great forum at www.torque-bhp.com. Their web site also recommends better quality readers than mine if you can afford it. I had to load one custom PID from within the app. There were two custom PIDs for transmision oil temp and the second one worked for me.

Can anyone recommend some products for someone that is just becoming interested in reading diagnostics for minor repairs and possibly things like monitoring trans temp during road trips? I have an iphone 5 and it seems that most of the OBD2 components are Android, I'd like to get something worth the money and it doesn't need to be bluetooth but would need to run with the Acadia moving. Thanks!

As long as you have the tow pkg there should be no problem. I towed a 4000 pound boat on a tandem trailer 1800 miles straight shotin 3 days and had no problems at all. Only mention I will make is that you may have to tow in 5th gear unless on the downhill or extremely flat terrain . Trying to tow in 6th gear it is hard to keep the RPM's above 2200 where it seems to tow best. I got somewhere around 15 mpg for trip.
